09CUPCINi-A weathering steel Manufacturing Process

09CUPCINi-A weathering steel generally adopts the process route of fine material entering the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining low superheat continuous casting (feeding rare earth wire)-controlled rolling and controlled cooling.

During the smelting, the scrap of 09CUPCINi-A weathering steel is added to the furnace along with the charge, and smelted according to the conventional process. After tapping, the deoxidizer and alloy are added. After the molten steel is treated by argon blowing, it will be cast immediately. The molten steel is cast into a slab by a continuous casting machine. Due to the addition of rare earth elements to 09CUPCINi-A weathering steel, 09CUPCINi-A weathering steel is purified, and the content of inclusions is greatly reduced.

The service life of 09CUPCINi-A weathering steel material is 8 times that of ordinary steel without any anti-corrosion treatment, and it can be used for more than 30 years with anti-rust paint.
